Problems solved by technology

And each blockchain will issue its corresponding digital currency, however, different digital currencies cannot be used universally between different blockchains
The same user may hold a variety of digital currencies, and since many countries currently prohibit the direct exchange of digital currencies and legal tenders (that is, prohibit the cashing of non-legal digital currencies), this makes it impossible for users to exchange between multiple different digital currencies

no. 1 example

[0076] see figure 1 , figure 1 It is a schematic flowchart of a digital currency transaction method provided by an embodiment of the present invention.

[0077] Such as figure 1 As shown, the method includes:

[0078] S100: When the first block chain initiates a transaction to the second block chain, and the number of nodes in the first block chain that agree to the transaction content corresponding to the transaction is greater than the preset first threshold, the first block chain The transaction generates the first block and sends the first block to the default settlement block chain.

[0079] It is well known that electronic transactions in the blockchain often use digital currencies. And each blockchain will issue its own digital currency. Then digital currency is not universal between blockchains. That is, in the prior art, the exchange between digital currencies cannot be realized.

[0080] However, in this embodiment, in order to solve the technical disadvantage...

no. 2 example

[0098] This embodiment is based on the first embodiment.

[0099] see figure 2 , figure 2 It is a schematic flow diagram of the first blockchain registration provided by the embodiment of the present invention.

[0100] combine figure 1 and figure 2 It can be seen that before S100, the method also includes:

[0101] S1: The first blockchain before registration will broadcast its corresponding first registration information in the settlement blockchain.

[0102] Preferably, the first registration information includes: the issuance speed Vac of the digital currency AC of the first block chain, the target average time Bat of the first block chain to generate a block, the calculation difficulty POWa of the first block chain, the first block chain The number of nodes Qan in a block chain.

[0103] Among them, once the target average time Bat for generating a block in the first blockchain is determined, it cannot be changed.

[0104] Of course, the first registration infor...

no. 3 example

[0116] This embodiment is based on the second embodiment.

[0117] see image 3 , image 3 It is a schematic flow diagram of the second blockchain registration provided by the embodiment of the present invention.

[0118] combine figure 1 with image 3 It can be seen that before S100, the method also includes:

[0119] S4: The second blockchain before registration broadcasts its corresponding second registration information in the settlement blockchain.

[0120] Preferably, the second registration information includes: the issuance speed Vbc of the digital currency BC of the second blockchain, the target average time Bbt of the second blockchain to generate a block, the calculation difficulty POWb of the second blockchain, the second blockchain The number of nodes Qbn of the second block chain.

[0121] Among them, once the target average time Bbt for generating a block in the second blockchain is determined, it cannot be changed.

[0122] Of course, the second registra...

Abstract

Embodiments of the present invention relate to a trading method and system for digital money. The method comprises: when the first block chain initiates a transaction to the second block chain, and the number of nodes in the first block chain agreeing to the transaction corresponding to the transaction is greater than a preset first threshold value, the first block chain generates a first block according to the transaction, and sends the first block to the preset settlement block chain; when the number of nodes in the second block chain agreeing to the transaction content is greater than a preset second threshold, the second block chain generates a second block according to the transaction, and sends the second block to the settlement block chain; the settlement block chain verifies the first block and the second block, and obtains the verification result. When the verification result is passed, the settlement block chain settles the transaction. The technical proposal provided by theembodiment realizes the exchange between different digital currencies so as to bring convenience to users and realize the technical effect of fully utilizing resources.

Description

technical field [0001] The embodiment of the present invention relates to the field of block chain technology, and in particular to a digital currency transaction method and system. Background technique [0002] With the development of science and technology, because the blockchain has the advantages of data security and transparency, blockchain-related technologies are widely used in trade, finance and other fields. [0003] As we all know, electronic transactions in the blockchain require the use of digital currency. And each blockchain will issue its corresponding digital currency, however, different digital currencies cannot be used universally between different blockchains. The same user may hold a variety of digital currencies, and since many countries currently prohibit the direct exchange of digital currencies and legal tenders (that is, prohibit the cashing of non-legal digital currencies), this makes it impossible for users to exchange between multiple different d...
